The Brazilian Northeast is the second most populous region the Brazil and presents, predominantly, semi-arid climate. Livestock farming has been one of the main skills of this region. Due to the rainfall irregularity observed in the Brazilian Semi-arid region, alternatives have been sought to overcome this situation, such as the cultivation of forage plants with xerophytic characteristics such as forage palm. H...
The antimicrobial use in poultry farming is a common practice around the world, aiming to increase animal productivity. However, the growing emergence of resistant bacterial species to these drugs has concerned poultry producers and consumers. Gram-positive bacteria as Enterococcus spp. and Staphylococcus aureus, and Gram-negative bacteria as Escherichia coli, Campylobacter spp. and Salmonella spp., are among t...
Mining is a worldwide activity of great importance due to the use of the metals that are extracted, like copper, in Brazil, with emphasis on the state of Pará. The objective of this research was to evaluate the potential, ie, ability, capacity of the species Schizolobium amazonicum, Leucaena leucocephala and Azadirachta indica submitted to soil contamination with copper mining tailings, to phytoremediate heavy ...
Wissadula periplocifolia (Malvaceae), commonly know in Brazil as “malva amarela”, is popularly used to treat snake bites and bee stings. A phytochemical study on its aerial parts using chromatographic techniques has led to the isolation of chlorophyll derivatives, terpenoids, phenolic acids and thirteen flavonoids, among them methoxylated flavones, glucosyl flavonoides and sulfated flavonoids, notably the new c...
The inselbergs are characterized by presenting more severe edaphoclimatic conditions in relation to the surrounding environment, exerting an important selective function for the evolution and vegetal speciation. The flora of the inselbergs can present morphological and chromosomal differentiation (levels of ploidy), making possible the evaluation of the mechanisms involved in the diversification of the species....
The present work is part of the studies that seek to represent and investigate linguistic systems using mathematical models. In such context, a Maximum Entropy model of phonotactics developed by Hayes and Wilson (2008) has exhibted a high level of accuracy in relation to experimental data when applied to English, outperforming other phonotactic modelling proposals. Nevertheless, despite its good results, we are...
Tomato (Solanum lycopersicum L.) is one of the most important oleraceous in the world, and it is subject to the attack of several pathogens, especially to the nematodes of the galls, that can promote physiological disorders that make the crop unviable. In view of this problem, it is necessary to search for strategies that minimize these effects, so the application of salicylic acid may be a promising strategy. ...
The experiment was carried out with the objective of evaluating the gene expression of the sodium and glucose co-transporter type 1 (SGLT1) and glucose transporters type 2 and 5 (GLUT2 and 5) in Japanese quails in different phases. Eighty-eight Japanese one-day-old female categories, reared in conditions similar to the creation of a production, with feed and water ad libitum, were used. The design was the casua...
To evaluate the effects of phytase supplementation was performed two experiments with quails and eat and laying. The objective was to evaluate the effects of phytase supplementation in the diet with reduced levels of available phosphorus, calcium, amino acids digestible and metabolizable energy for quails in performance parameters, carcass traits, intestinal morphology and bone strength. 680 European quails (Co...
The objective of this study was to evaluate the effects of supplementation with non-protein nitrogen (NNP) on the intake, digestibility, ruminal parameters and nitrogen balance of goats fed buffelgrass hay. Five goats with no defined racial pattern (NDRP), adults, castrated and cannulated in the rumen were used, with an average weight of 45 ± 2,3 kg. Five diets were provided, where the control treatment consist...
